3 Claims. (Cl. 229-14) Liners of that type that have heretofore beenproposed have required an excessive amount of time and labor to foldthem into proper condition for insertion in the carton. While suchliners serve to protect the packed articles from being broken or damagedin transit, especially in the case of light-weight fragile articles,nevertheless their use has hitherto been limited because of theabovenoted objection, as well as for other reasons.

With the defects of the prior art liners in mind, it is an object of myinvention to provide an improved foldable liner that upon being foldedfor insertion into a carton has self-forming corner pieces that act asstruts to space the side walls of the liner inwardly from thecorresponding side walls of the carton and hold them in such spacedrelation.

Another object of my invention is to provide a foldable liner that caneasily be formed in condition for insertion into a carton with a minimumexpenditure of time and labor.

Still another object is. to provide a foldable liner of simple andinexpensive construction, the body of the liner being formed entirely ofa one-piece foldable blank.

A further object is to provide a liner comprising a one-piece bodymember that can be readily folded manually into shape by merely bendingup the side portions thereof, whereupon the corner portions will beselfformed, or that can be automatically folded by placing the blank incentralized position on the top of the open carton, and then applyingdownward pressure on that portion 'of the blank that will constiute thebottom of the inserted liner.

Ather objects and advantages of the invention will appear from thefollowing description thereof, reference being had to the accompanyingdrawings, in which:

Fig. 1 is a perspective view of a conventional form of carton in whichmy improved liner hasbeen inserted;

Fig. 2 is a longitudinal cross-sectional view taken on the line 2-2 ofFig. 1; I

Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 1; I

Fig. 4 is a top sectional view taken on the line 4-4 of Fig. 1;

Fig. 5 is an exploded view in perspective of the folded liner blank andits cover member;

Fig. 6 is a plan view of the liner blank in its normal flat state beforebeing folded, the dash lines on the face of the blank indicating thescoring along which the blank will fold; and v Fig. 7 is a perspectiveview of the blank in partly folded condition.

The carton or outer container 10 is of the conventional type used inshipping light-weight articles. It is generally rectangular in shape andmade of corrugated ice paperboard or the like. No invention is claimedin the carton per se.

The improved foldable liner to which this invention particularly relatescomprises a body member 11, which member is made of a cut and scoredblank 12 consisting of .a single flat sheet of paperboard, such ascorrugated paperboard, or other suitable material. A preferred form ofblank is shown in Fig. 6 in which the cut edges are delineated in solidlines, while the scored portions, along which the blank is to be foldedto form the liner body member 11, are indicated by dash or broken lines.The liner may be provided with a cover member 13, preferably made of thesame material as the blank 12.

The blank 12 has a substantially rectangular central portion 14 thatforms the bottom of the liner body member 11 when the blank is folded.Along the four sides of the central portion 14 are mutually opposedparallel side portions 1515 and 16-16, which side portions are definedby scores 17 and 18, and cuts 19, 20, and 21, respectively. The cuts 19and 21 extend inwardly to form integral extensions 22 and 23 of the sidewalls that, when the blank is folded, serve as legs for supporting theliner body member in the carton with its bottom 14 spaced from and abovethe bottom of the carton. The cuts 20 extend outwardly from the centralportion 14 of the blank to form integral projections 24 of said portion,which projections 24 serve as additional means for spacing the walls ofthe liner inward from the walls of the carton. If desired, theseprojections may be eliminated.

The side and end wall portions 15 and 16 respectively are connected bycorner portions 25 each of which has a reentering right-angle, and ascore 26 that runs from a corner of the central portion 14 to the vertexof the angle. When the blank is folded, the two parts of each angleportion are brought together in facial contact with each other to formthe corner struts 27, as best seen in Figs. 4 and 5, which struts holdthe liner body member spaced inward from the corners and sides of thecarton. On folding the blank, the scores 26 form the inclined bottomedges 28 of the struts.

The outer edges of the side portions of the blank 12 may have cut-outsor recesses 29 and 30 formed therein. In the particular form of blankshown, the cut-outs 29 of the side portion 15 are spaced apart to leaveintervening portions or tongues 31 which tongues are adapted forinsertion in the slots or openings 32 in the liner cover member 13, asseen in Fig. 4. The ends 33 of the cover member may be shaped, as shown,to seat in the recesses 30 of the body member. Upstanding flanges 34 maybe formed along the sides of the cover. It will be understood thatinstead of having the ends of the cover seat in recesses, the body andcover may be formed with tongues 31 and slots 32 at all four sidesinstead of at two of the sides, only.

To form the blank into condition for insertion into the carton, it ismerely necessary to bend the side portions A-A and B-B upwardly, asindicated in Fig. 7. On so bending the side portions, the four cornerportions will be self-bent upwardly and outwardly in position, forinsertion into the carton without the necessity for any further oradditional operation. As an alternative, the blank may be automaticallyformed into shape by laying it in centralized position over the open topof the carton and pressing it into the carton by application of downwardpressure against its bottom C as indicated by the vertical arrow in Fig.7. In either case the corner struts will be self-forming.

It is to be understood that while I prefer to employ a blank having asubstantially rectangular central portion, that portion may be of othersuitable shapes, de-

liner for removable insertion into the carton, which liner comprises aflat horizontal bottom portion, vertical side and end portions, saidside and end portions having integral projections that extend downwardlyfrom their lower edges to provide legs for supporting the bottom portionof the liner upwardly from the bottom of the carton, and outwardlyextending integral corner portions at the four corners of the linerbetween the side and end wall portions thereof to space said wallsinwardly from the corresponding walls of the carton.

2. In combination with a shipping carton, a one-piece liner forremovable insertion into the carton, which liner comprises a flathorizontal bottom portion, vertical side and end portions, said side andend portions having integral projections that extend downwardly fromtheir lower edges to provide legs for supporting the bottom portion ofthe liner upwardly from the bottom of the carton, and outwardlyextending integral corner portions at the four corners of the linerbetween the side and end wall portions thereof to space said wallsinwardly from the corresponding walls ofthe carton, the upper ends ofsaid corner portions extending upwardly above the upper edges of theside and end walls to space the liner downwardly from the top of thecarton.

3. In combination with a shipping carton, a onepiece liner for removableinsertion into the carton, which liner comprises a flat horizontalbottom portion, vertical side and end portions, said side and endportions having integral projections that extend downwardly from theirlower edges to provide legs for supporting the bottom portion of theliner upwardly from the bottom of the carton, outwardly extendingintegral corner portions at the four corners of the liner between theside and end wall portions thereof to space said walls inwardly from thecorresponding walls of the carton, the upper ends of said cornerportions extending upwardly above the upper edges of the side and endwalls to space the liner downwardly from the top of the carton, and adetachable cover member supported on the upper edge of the side and endwalls with the corner pieces extending upwardly above the plane of thecover member.
